Nemaha is a tiny town in northwest Iowa located equidistant between Sioux City and Fort Dodge (and locally between Storm Lake and Sac City) at the intersection of county roads M50 and D15.
The population is around 100 people, down from almost 200 recorded in 1914. It was platted in 1899 at the northwest corner of Section 22 in Delaware Township, Sac County, Iowa. The town incorporated in 1914 and has remained incorporated ever since with a very active city council who strive to keep the town alive and presentable.
The name of Nemaha is an Indian word meaning "muddy water". This was characteristic of the level land at the time since much of it was swampy. Telephones came to town about 1907 with a magnetic exchange that required a full-time operator. Electricity arrived around 1918.
